Error message on boot

I have just installed coda on two Redhat 6.1 systems. Both
are running the 2.2.14 kernel. When both systems boot up,
the following message is displayed:
kernel: coda_psdev_write: downcall, no SB!
I've checked numerous sources, including the coldalist archives,
and found no reference to the above message. The message
occurs as venus.init is starting. Both the 5.3.5-1 server and
client were installed. Another message that came up was:
Kernel version ioctl failed (Inappropriate ioctl for device)!
Anyone have any ideas what the problems may be?
Thanks in advance.
Vic.
